Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528722, here are decompositions:

3 + 528719 = 528722
13 + 528709 = 528722
31 + 528691 = 528722
43 + 528679 = 528722
163 + 528559 = 528722
211 + 528511 = 528722
331 + 528391 = 528722
349 + 528373 = 528722

Showing the first eight; more decompositions exist.
